rde/menutree

選單樹

MenuTree

, _(*1)

Installation：

``` json { "require": { "rde/menutree": "0.2.*@dev" } }, <sub>(*2)</sub>

* PHP環境需要pdo_sqlite pdo_mysql (預設載體)
* 把db_schema資料夾裡的sql 部屬在database。
* 預設資料載體sqlite (/src/storage/menudata.slite3) 裡面的資料格式 （id, item_id, parent_id, depth, left, right, url_name, url），其中item_id為不可重複的唯一key，可用字串，如不小心寫入重複key，在MenuData取資料時也會慮掉重複字串。id為一般流水號，其他欄位可填可不填。
* 唯一要注意，如果此比資料為樹狀資料最上層，其parnet_id 要填入字串'null'
* 也可各自實現IMenuProvider & IUserProvider 來使用自己儲存體


Usage：
---------------

``` php
/*
假設原始資料為:
array(
    array(
    "id" => 1,
    "item_id" => key_1,
    "parent_id" => 'null'
    "depth" => 0,
    "left" => 1,
    "right" => 2,
    "url_name" => test1,
    "url" => contorller1/method1
    ),
    array(
    "id" => 2,
    "item_id" => key_2,
    "parent_id" => key_1,
    "depth" => 1,
    "left" => 3,
    "right" => 4,
    "url_name" => test2,
    "url" => contorller2/method2
    ),
);
*/


//可自行實作使用者選單，只要最後給MenuData的過濾資料格式如下面範例即可
$pdo_mysql = new PDO('mysql:host=127.0.0.1;dbname=account','root','xxxx');
$user = new User($pdo_mysql);

//find_menu() 會用array回傳 每個item_id  ex array(key_1,key_2...)
//建構參數pdo 可選填，沒填預設會讀取src/storage/menudata.sqlite3 裡的資料
$menuOrigin = new MenuData();


$insertData = array(
    array(
        "id" => 1,
        "item_id" => key_3,
        "parent_id" => 'key_1'
        "depth" => 0,
        "left" => 1,
        "right" => 2,
        "url_name" => test3,
        "url" => contorller3/method3
        ),
);
/*
結果為
array(
    array(
    "id" => 1,
    "item_id" => key_1,
    "parent_id" => 'null'
    "depth" => 0,
    "left" => 1,
    "right" => 2,
    "url_name" => test1,
    "url" => contorller1/method1

    array(
    "id" => 1,
    "item_id" => key_3,
    "parent_id" => 'key_1'
    "depth" => 0,
    "left" => 1,
    "right" => 2,
    "url_name" => test3,
    "url" => contorller3/method3
    ),
    array(
    "id" => 2,
    "item_id" => key_2,
    "parent_id" => key_1,
    "depth" => 1,
    "left" => 3,
    "right" => 4,
    "url_name" => test2,
    "url" => contorller2/method2
    ),
);
*/

//建構選單樹狀物件
$menutree = new MenuTree($menuOrigin); 

//可拿到完整的樹狀結構
$tree = $menutree->get(); 
/*
最後get回來的資料格式如以下:
array(
    array(
        "deep" => 0,
        "self" => array(
            "id" => 1,

            "url_name" => test1,
            "url" => contorller1/method1
